有时,Windows 资源管理器显示图标有问题。比如我们升级了PowerShell 5.0以后,PowerShell和PowerShell ISE 的图标被更新成了modern风格。如果你看到的还是旧的图标,那可能就是缓存问题导致的。这里分享一个函数,可以帮助我们通过调用原生态的Windows API,强制刷新Windows图标缓存。
function Update-ExplorerIcon { [CmdletBinding()] param() $code = @' private static readonly IntPtr HWND_BROADCAST = new IntPtr(0xffff); private const int WM_SETTINGCHANGE = 0x1a; private const int SMTO_ABORTIFHUNG = 0x0002; [System.Runtime.InteropServices.DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)] static extern bool SendNotifyMessage(IntPtr hWnd, uint Msg, UIntPtr wParam, IntPtr lParam); [System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true)] private static extern IntPtr SendMessageTimeout ( IntPtr hWnd, int Msg, IntPtr wParam, string lParam, uint fuFlags, uint uTimeout, IntPtr lpdwResult ); [System.Runtime.InteropServices.DllImport("Shell32.dll")] private static extern int SHChangeNotify(int eventId, int flags, IntPtr item1, IntPtr item2); public static void Refresh() { SHChangeNotify(0x8000000, 0x1000, IntPtr.Zero, IntPtr.Zero); SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, IntPtr.Zero, null, SMTO_ABORTIFHUNG, 100, IntPtr.Zero); } '@ Add-Type -MemberDefinition $code -Namespace MyWinAPI -Name Explorer [MyWinAPI.Explorer]::Refresh() }
